Description of Related Art

With the development of display technologies, the demand for display devices is no longer limited to favorable optical characteristics, such as high resolution, high contrast, and wide viewing angles. People also expect the display devices to have elegant appearance. For instance, people expect the display devices to have narrow frames or even to be frameless.

Generally speaking, the display device includes a pixel array disposed in a display region, a data driving circuit disposed below the display region, and a gate driving circuit disposed on the left side, the right side, or both the left and the right sides of the display region. In order to reduce the width of the left and right sides of the frame of the display device, both the gate driving circuit and the data driving circuit may be disposed on the lower side of the display region. When the gate driving circuit is disposed on the lower side of the display region, a gate line extending in a horizontal direction can merely be electrically connected to the gate driving circuit through a transfer line extending in a vertical direction. The transfer line, however, occupies the layout area of the display region, and the number of circuits in the display region also increases, thus affecting an aperture ratio of a pixel array substrate of the display device and the manufacturing yield.

In particular, a line width W1 of the first portion gla-1 of the transfer line gl is larger than a line width W2 of the second portion gla-2 of the transfer line gl.

That is, in this embodiment, each of the transfer lines gl may be formed by connecting the main portion gla belonging to different conductive layers and a plurality of auxiliary portions glb in parallel, so as to reduce the resistance value.

For instance, in this embodiment, the main portion gla of each transfer line gl may be selectively formed in the second metal layer, and the at least one auxiliary portion glb of each transfer line gl may be selectively formed in the first metal layer, the two ends of each of the at least one auxiliary portion glb may be electrically connected to the two different regions of the main portion gla through the second through hole 130 b of the insulation layer 130, which should however not be construed as a limitation in the disclosure.

FIG. 16 shows signals of a plurality of transfer lines gl1-gl14 (or a plurality of gate lines GL1-GL14) during a reverse scan of the pixel array substrate 100 according to an embodiment of the disclosure.

With reference to FIG. 2 and FIG. 16, the pixels 120 include a plurality of pixel groups GP. Each pixel group GP includes one first pixel 120A and n second pixels 120C sequentially arranged along one transfer line gl (e.g., gl14). The n second pixels 120C and one first pixel 120A are sequentially arranged in a reverse scan direction (e.g., the opposite direction of the second direction y), and the gate line GL (e.g., GL14) electrically connected to the first pixel 120A is electrically connected to the transfer line gl (e.g., gl14) through the first through hole 130 a of the insulation layer 130, wherein n is a positive integer greater than or equal to 2. In other words, in the same pixel group GP, another second pixel 120C is disposed between the first pixel 120A and one second pixel 120C disposed corresponding to the first through hole 130 a.

In this embodiment, the first pixel 120A of each pixel group GP is the pixel 120 closest to the second pixel 120C of the pixel group GP, and the first pixels 120A of the pixel groups GP are arranged substantially in a staircase shape.

In this embodiment, the number n of the second pixels 120C of each pixel group GP may be determined according to a driving method of the gate lines GL (or a driving method of the transfer lines gl).

Specifically, in this embodiment, the gate lines GL are divided into a plurality of gate line groups K, each of the gate line groups K includes m gate lines, and m gate lines GL of the same gate line group K are simultaneously turned on, wherein m is a positive integer greater than or equal to 1; when each of the gate line groups K is turned on, each of the m gate lines GL of the gate line group K has a gate-on pulse, and a time length of the gate pulse is T; the gate line groups K are sequentially turned on with a time delay, a time length of the time delay is t, n≥{[(Tt/t]*m}+m, T=kt, and k is a positive integer greater than or equal to 1.

For instance, in this embodiment, the gate lines GL are divided into a plurality of gate line groups K, and each of the gate line groups K includes 2 gate lines GL (i.e., m=2), two gate lines GL of the same gate line group K are turned on at the same time. When each of the gate line groups K is turned on, each of the two gate lines GL of the gate line group K has the gate-on pulse, k=5, and the time length of the gate pulse T=5t, n≥{[(5t−t)/t]*2}+2, i.e., n≥10. That is, in this embodiment, the number of the second pixel 120Cs of one pixel group GP is greater than or equal to 10, e.g., 11 or 12; however, the disclosure is not limited thereto. According to this embodiment, note that k being 5 is merely exemplary, which should however not be construed as a limitation in the disclosure. In other embodiments, k may be a positive integer other than 5 and greater than or equal to 1.

In the same pixel group GP, one gate line GL (e.g., GL14) electrically connected to the first second pixel 120C has a gate-on potential in a time interval T1, and another gate line GL (e.g., GL2) electrically connected to the first pixel 120A has the gate-on potential in a time interval T7. The time interval T1 and the time interval T7 are not overlapped in time sequence.

That is, when the gate line GL2 has the gate-on potential and the first pixel 120A of the pixel group GP is charged, the signal of the transfer line gl14 adjacent to the first pixel 120A has been switched to a gate-off potential; therefore, even though the pixel electrode 122 of the first pixel 120A and the transfer line gl14 are partially overlapped, the signal of the transfer line gl14 does not easily affect the potential of the pixel electrode 122 of the first pixel 120A.

On the other hand, in the same pixel group GP1, the gate lines GL13-GL5 that are electrically connected to other second pixels 120C (e.g., the second to ten second pixels 120C) respectively have the gate-on potential in the time intervals T1, T2, T3, T3, and T5. When the gate lines GL13-GL5 have the gate-on potential and other second pixels 120C (e.g., the second to ten second pixels 120C) are charged, the signal of the transfer line gl14 adjacent to other second pixels 120C (e.g., the second to ten second pixels 120C) is switched from the gate-on potential to the gate-off potential. However, the pixel electrodes 122 of other second pixels 120C (e.g., the second to ten second pixels 120C) do not overlap the transfer line gl14, and the parasitic capacitance between the transfer line gl14 and the pixel electrodes 122 of other second pixels 120C (e.g., the second to ten second pixels 120C) is small; therefore, the change of the signal of the transfer line gl14 does not easily affect the potentials of the pixel electrodes 122 of other second pixels 120C (e.g., the second to ten second pixels 120C).

According to this embodiment, note that the pixel electrode 122 of the first pixel 120A and the transfer line gl are overlapped, and the area occupied by the pixel electrode 122 of the first pixel 120A is large, which is conducive to the improvement of the aperture ratio of the pixel array substrate 100. In addition, in this embodiment, the transfer line gl may include the main portion gla and the at least one auxiliary portion glb which belong to two different electrical metal layers and are electrically connected to each other through the second through hole 130 b, i.e., the transfer line gl may have a double-layer metal wiring design, which is conducive to the reduction of the overall resistance value of the transfer line gl, so that the pixel array substrate 100 may be easily driven. The pixel electrode 122 of the second pixel 120C and the transfer line gl are not overlapped, and the potential of the pixel electrode 122 of the second pixel 120C is not easily affected by the parasitic capacitance between the transfer line gl and the pixel electrode 122 of the second pixel 120C. In this embodiment, the positions of the first pixels 120A and the positions of the second pixels 120C appropriately arranged according to the driving method of the gate lines GL, so as to form the pixel array substrate 100 which has the high aperture ratio and may be easily driven.

In the embodiment shown in FIG. 16, the pixel array substrate 100 is driven in a reverse scan manner. However, the pixel array substrate 100 is not limited to being driven in a forward scan manner or the reverse scan manner. FIG. 17 shows signals of the transfer lines gl1-gl14 (or the gate lines GL1-GL14) during a forward scan of the pixel array substrate 100 according to an embodiment of the disclosure. The pixel array substrate 100 shown in FIG. 2 may also be driven in the forward scan manner shown in FIG. 1 7.

In particular, the structure of the first pixel 120A-1, the structure of the second pixel 120C-1, and the structure of the second pixel 120C-4 are different from one another.

With reference to FIG. 2 and FIG. 3, specifically, in this embodiment, the transfer line gl of the first pixel 120A-1 and the pixel electrode 122 of the first pixel 120A-1 are partially overlapped.

A gap G exists between the pixel electrode 122 of the second pixel 120C-1 and the transfer line gl of the second pixel 120C-1, and one portion of the transfer line gl of the second pixel 120C-1 crosses over one gate line GL electrically connected to the active device 121 of the second pixel 120C (i.e., one portion of the transfer line gl of the second pixel 120C-1 is electrically independent from the active device 121 of the second pixel 120C), which is different from that in the first pixel 120A-1.

With reference to FIG. 2 and FIG. 11, the pixel electrode 122 of the second pixel 120C-4 and the common electrode el of the second pixel 120C-4 are partially overlapped, and the common electrode el of the second pixel 120C-4 and one portion of the transfer line gl of the second pixel 120C-4 are overlapped.

One portion of the transfer line gl of the second pixel 120C-4 is a gate line GL electrically connected to the active device 121 electrically connected to the second pixel 120C-4, which is different from that in the second pixel 120C-1.
